Viewing Device Details of a CSD-Topology for Examining Traffic Transmission

 

You can view the details of all of the devices or nodes in a Topology View that are managed by the CSD-Topology. Node addresses for the Node A and Node Z elements define the endpoint nodes for the tunnel. Devices that are discovered as part of the topology acquisition by the CSD-Topology and are not managed devices in the Connectivity Services Director database are displayed in gray. Devices that are discovered by the CSD-Topology using BGP and MPLS and are managed devices in the Connectivity Services Director database are displayed in blue.

Note

Because of the way in which the link-state database (LSDB) interior gateway protocols (IGPs) represent LAN connections (in order to improve scaling), multiple entries for the same hostname might be displayed on the Devices tab of the Topology View. Similarly, multiple entries for the same hostname might be displayed on the Devices tab because of the manner in which OSPF and ISIS associate with broadcast interfaces. The pseudonodes are represented in a distinct way on the GUI. When the IGP (OSPF or ISIS) builds neighboring relationships on broadcast media (such as Ethernet), the IGP represents this deployment as a hub-and-spoke topology with all nodes in the same broadcast domain having a point-to-point connection with a pseudonode. In such instances, the traffic engineering database includes a pseudonode on each interface that is configured with the interface-type LAN (the default). If such pseudonodes are not added, the topology displays a full-mesh of point-to-point connections between all nodes in the same LAN segment (this case occurs if you manually configure the interface type as point-to-multipoint [P2MP], and manually add each neighbor). The GUI represents these pseudonodes in a way that enables you to easily see that these are not real nodes (it can represent the pseudonode as a different entity, such as a special node or a LAN segment).

To view details of devices or nodes in the Topology View:

  1. From the Junos Space user interface, click the Build icon on the Connectivity Services Director banner.

    The workspaces that are applicable to Build mode are displayed on the Tasks pane.

  2. From the View selector, select Topology View.

    The topology map of the sites or zones and the devices configured in each zone using the CSD-Topology is displayed on the upper portion of the page. A table with details of devices, services, links, and LSPs is displayed on the lower portion of the page.

  3. Select the Devices tab on the lower portion of the page.

    For columns in the table that contain an empty text field displayed at the top of the table on each tab, you can enter the search criterion that you want to use for that particular column or parameter to sort and classify the display of values in the table. For parameters that you can enable or disable, you can select or clear the check boxes respectively. The page is refreshed to display the devices that match the specified criterion. The search criteria that you have entered are displayed above the first row of the table. You can click Clear All displayed beside each of the search terms to remove the previously defined search terms.

    • Name—Hostname of the device. Click in the first cell in this column to enter the hostname as the criterion for filtering and displaying the devices in the table.

    • Management Address—Management IP address of the node. Click in the first cell in this column to enter the management IP address as the criterion for filtering and displaying the devices in the table.

    • Serial Number—Hardware serial number of the device

    • Software Version—Junos OS software version and release number running on the device

    • Platform—Platform type of the device, such as MX240 or MX480

    • Platform Series—Device family to which the device belongs, such as MX Series for an MX240 router
